Question

speed of train is 15 m/ s and train length is 90 m time taken to cross a tree. ???​

Answer 1

Given :

Speed of train = 90 kmph

Length of train = 150 m

Length of platform = 300 m

To find :

Time taken to cross the platform

Formula used :

Time = (distance)/(speed)

Calculation :

Total length = length of train + length of platform

⇒ Total length = 150 + 300

⇒ Total length = 450 m

⇒ Speed of train = 90 × (5/18)

⇒ Speed of train = 25 m/s

⇒ Time taken = 450/25

⇒ Time taken = 18

∴ The time taken to cross the platform is 18 seconds.

Answer 2

Answer:

6 second

Step-by-step explanation:

speed of train :- 15m/s
